Phillip Schofield posts photo of Holly Willoughby 'passed out' after they share of bottle of tequila
The pair were filming their appearance on Alan Carr: Chatty Man and started off the evening looking rather civilised in a snap with the comedian - but things soon went downhill.
'This was the end,' Tweeted Phillip, 50, along with a photo of Holly apparently passed out on the table next to the empty bottle of alcohol.
Holly reveals on the show that she'd drunk Agave tequila before and had escaped a hangover - so the pair decided to see if the same would happen again.
Phillip happily admitted he was 'pissed' after they finished the bottle - but he was feeling 'bright as a button' the following day.
'Remarkable! @hollywills was right, I can confirm that the #tequilaexperiment was a success!!' Tweeted Phillip.
Holly, 31, writes this morning: 'For the record... That tequila pic was a joke?... But I did eat a few of the crisps! X.'
